Definitions

  • the Present Disclosure relates, generally, to cable interconnection systems, and, more particularly, to improved, rattle-free connectors used in motive environments.
  • the Present Disclosure is therefore directed to a connector construction, particularly suitable for use in a USB style application, that has improved retention capabilities.
  • an improved and economical connector structure that has improved retention capabilities capable of withstanding dynamic and shock loads that normally occur in vehicle operation.
  • a connector of the USB-style is adapted to fit into a frame, or bezel plate, that positions the connector in place within a vehicle, such as on a console, dashboard, seatback or the like.
  • the receptacle connector supports a plurality of conductive terminals within it that are capable of high speed data transmission and the terminals may be arranged either on a mating blade or in a receptacle.
  • the terminals may be surrounded by a grounding shield.
  • the terminals have tails, or termination ends, that are terminated to wires of a multiple wire cable and this area is covered by a protective housing.
  • This protective housing has a body portion that typically encloses the entire termination area and provides a means by which it is attached to the cable. In most applications, the protective housing may be overmolded over both an end of the cable and the terminal support of the connector.
  • the protective housing of the Present Disclosure has at least one, and preferably two, exterior engagement arms that are configured to extend outwardly away from the protective housing. In one embodiment of the Present Disclosure, the arms are formed integrally with the housing and extend outwardly therefrom. The arms are attached, at their opposing ends, to the body of the housing and are spaced away from the housing by an intervening, captured space therebetween.
  • the intervening space that extends between the engagement arm ends is preferably formed with a shape that biases the engagement arms outwardly away from the housing body portion so that the arms will apply an outward force against any opposing surface of a frame into which the connector is inserted.
  • This outward biasing force urges the connector housing rearwardly against angled interior walls of the frame member causing the connector housing catches, or lock members into contact with opposing stop surface.
  • the exterior engagement arms of the connector may be reinforced by a flexible insert that is positioned in the mold prior to overmolding the housing.
  • a flexible insert will be a strip of metal that has elastic properties sufficient to prevent any permanent deformation of the engagement arms due to shock or other dynamic loading.
  • the engagement arms may be separately formed, such as form a metal or plastic and attached to the connector housing body in a suitable manner.
  • FIG. 1 is a perspective view of a receptacle connector in accordance with the Present Disclosure, and a housing that receives the connector and defines an opening of an opposing, mating connector;
  • FIG. 2 is a rear view of the connector and housing of FIG. 1 , taken from the rear thereof, and illustrating the connector and housing in an assembled condition;
  • FIG. 3 is an exploded view of the receptacle connector of FIG. 1 ;

  • the terminals 28 are supported in part by a mating blade 27 formed of an insulative material, and illustrated as a male mating blade 27 having a plurality of terminal-receiving cavities 39 , each of which receives a single terminal 28 therein.
  • the terminals 28 are shown as having a stepped configuration, with the terminal tails, or terminations portions 28 b being spaced apart from the terminal body portions 28 c . These tails 28 b may be terminated directly to individual wires of the cable 21 , or they may be terminated to or supported by a circuit board (not shown). In either configuration, the area surrounding the terminal tails hereinafter is referred to as the “termination area,” and this area is enclosed by a mass 26 of epoxy, other curable material or a plastic to form a premolded, internal body portion 40 of the connector 20 that includes the mass 26 , and portions of the terminals 28 and the mating blade 27 .
  • An exterior shield 23 is preferably provided and may be formed in a conventional manner from sheet metal stamped and formed to define a hollow enclosure, bounded by four walls and having an internal cavity 25 .
  • the shield walls may have grounding springs 24 formed therein at desired intervals to provide a means of connection between the connector 20 and an opposing, mating connector (not shown) as well as to provide desired grounding contact around the perimeter of the mating blade 27 so as to provide a measure of EMI (“electromagnetic interference”) protection.
  • a protective housing 22 is provided over the internal body portion 40 and parts of the shield 23 and cable 21 .
  • the protective housing 22 is shown as having a catch member, or connector lock member, 29 rising up from an exterior surface thereof and disposed between two upright rail members 42 , and the catch member 29 may be positioned so as to engage a latch opening 19 disposed in the frame member 12 .
  • the frame member 12 may include a pair of slots 43 that flank the latch opening 19 and which also receive the connector rail members 42 .
  • a deflectable latching member, or tab, 45 is defined in the frame member 12 which is engaged by the catch member 29 when the connector 20 is fully inserted into the frame member 12 and therefore serves as a means by which to lock the connector 20 in place within the frame member 12 .
  • the frame member 12 has two latch openings 19 disposed therein on opposite sides (top and bottom).
  • the connector 20 includes two opposing positioned catch members or connector lock members 29 .
  • the protective housing 22 is preferably molded over the mating blade 27 , the terminals 28 housed in the mating blade terminal-receiving cavities 39 , a portion of the cable 21 and the mass 26 of that fills in the termination area.
  • This protective housing 22 may include a collar portion 30 that extends away from the rear of the protective housing 22 , and which contacts the cable 21 to not only secure the protective housing 22 to the cable 21 , but also to provide a strain relief member to the overall connector-cable assembly.
  • the central part of the protective housing 22 may be considered as defining a body portion 35 that encloses the termination area and holds some of the connector components together such as the mating blade 27 , inner mass 26 and shield in place with the cable 21 .
  • the housing body portion 35 may include a front skirt portion 31 that extends around the perimeter of the shield 23 .
  • the protective housing 22 fits inside of the inner cavity 15 of the frame member 12 .
  • the protective housing 22 includes a pair of engagement members that take the form of engagement arms 32 that extend lengthwise along the exterior of the protective housing 22 .
  • the arms each include an elongated backbone portion 34 that extends lengthwise and which terminates in two opposing ends 34 a , 34 b .
  • Each engagement arm 32 is separated, or spaced apart from the protective housing 22 and particularly, its body portion 35 by way of an intervening opening 36 , or spacing. This opening 36 defines an area alongside the protective housing 22 for the associated engagement arm 32 to deflect into during insertion into and removal of the connector 20 from the frame 12 .
  • the opening 36 is not uniform in its lengthwise extent along the protective housing 22 and as shown in FIG. 4 , the opening has different first and second widths, or spacings W 1 and W 2 .
  • the first opposing end 34 a may be considered as a distal end of its associated engagement arm 32 while the second opposing end 34 b may be considered as a proximal end of the engagement arm 32 .
  • the first width W 1 is associated with distal end 34 a
  • the second width W 2 is associated with proximal end 34 b .
  • the second width W 2 is preferably greater than the first width W 1 as shown in FIG.
  • the proximal end 34 b of the engagement arm 32 will act as a spring to urge the engagement arm 32 outward, even when the engagement arm 32 is deflected, under load.
  • the spring action of these engagement arms is dependent on their length so the proximal end 34 b provides its associated engagement arm 32 with a reliable outward bias that urges the engagement arm 32 away from the protective housing 22 .
  • each engagement arm 32 is provided with a protrusion 33 that extends outwardly to provide an engagement member that can reliably engage the interior of the frame connector-receiving cavity 15 and particularly the sidewalls 18 a , 18 b thereof.
  • the protrusion 33 is shown as a semi-circular member, but it will be understood that other suitable shapes may be used, such as one with a flat shoulder that may serve as an engagement surface.
  • FIG. 5A One manner of this type of connector engagement is illustrated in FIG. 5A where it can be seen that the frame member inner sidewalls 18 a , 18 b have been provided with recesses 46 that are complimentary in configuration to the protrusions 33 .
  • the greater width W 2 of the engagement arm proximal end urges the engagement arm 32 outwardly along the line of action designated by Arrow EA.
  • This outward bias urges the proximal engagement arm to move outwardly away from the protective housing and thereby always exert a positive and reliable force outwardly that maintains pressure against the frame member and particularly the inner sidewalls 18 a , 18 b thereof.
  • the protrusions 33 of the engagement arms 32 are maintained in place in the recesses 46 and in contact with the frame member 12 .
  • the frame member 12 utilize generally flat surfaces as its inner sidewalls 18 a , 18 b so that the structure of the connector 20 maintains a positive outward pressure of the engagement arms 32 on the sidewalls 18 a , 18 b of the frame member 12 , as illustrated in FIG. 5B , to resist dynamic and shock loads associated with vehicle operation.
  • These inner sidewalls 18 a , 18 b are angled outwardly as illustrated so that the outward pressure biases the connector 20 against the flat sidewalls 18 a , 18 b to urge the connector rearwardly within the connector-receiving cavity of the frame member 12 . This rearward bias moves the connector catch members 29 against the stop surfaces 50 of the frame member openings 19 ( FIGS.
  • the latch tab 45 of the frame is the only external latching member needed.
  • the protrusions 33 are preferably located forwardly of the catch 29 or along or rearwardly of the location where the terminal tail termination occurs.
  • FIG. 6A illustrates another embodiment of a connector constructed in accordance with the principles of the Present Disclosure where a flexible insert 50 is provided to reinforce the engagement arm 32 .
  • the insert 50 may be formed from either a plastic or preferably sheet metal and it is desired that the insert have elastic properties that permit it to bend during insertion without any permanent deformation.
  • the insert 50 may have its opposite ends 51 , 52 extend into the body portion 35 of the protective housing 22 as illustrated or they may end near the junction of the engagement arm ends and the protective housing 22 .
  • the engagement arms may be formed as separate members 60 that have ends 61 , 62 which extend into slots 64 of the protective housing 22 and which may be joined together by plastics welding or other suitable means.
